Abstract: System and method for simultaneously tracking a position of a medical device and ablating a tissue within a body. The system includes a power supply, a navigation device, and a control circuit. The power supply generates a current that is suitable for ablating tissue, such as heart tissue. The navigation device establishes a three-dimensional reference coordinate system and identifies a location of an energy delivery device in relation to the established coordinate system. The control circuit switches or alternates between activating the power supply and acquiring ultrasound data that identifies the location of the medical device within the established coordinate system.
